CU LTIVATO R.

SPECIFICATION forming part of Letters PatentNo 223,954, dated January2', 1880.

Application led March 25, 1879.

To all whom it may concern:

Be it known that I, BENJAMIN M. Roo'r, of Mount Joy, in the county of Lancaster, in the State of Pennsylvania, have made certain new and useful Improvements in Cultivators, of which the following is a full, clear, and exact specification, reference being had to t-he a'ccompanying drawings, making part hereof.

. My invention relates to that class of cultivators in which the frame is supported by two wheels and crank-axle, and from the frame of which hang a number of shovels; the -whole being drawn by two horses.

This machineis used for preparin g the ground for seeding, as a marker, and for cultivating corn, tobacco, &c.; and it consists in improvements fully described in the following specification and set forth in the appended claims.

In the drawings, Figure l represents a perspective view of a cultivator embodying my improvements. Fig. 2 is a `section showing the mechanism for raising and lowering the frame and the spades. Fig. 3 is a perspective view of the support for the rear spades. Fig.

4 is a perspective view of the support for the front spades. Fig. 5 is a perspective view of the casting which guides and supports the pole, and from which is suspended the doublel so tree.

Like letters of reference correspond to like parts.

A A are the side timbers of the frame, which are secured together by the casting P and timbers B and C. Immediately under the frame is supported the shaft Din bearings. To either end of this shaftrD are cranks E E', the crank-pins being the axes of the wheels F F. Upon shaftD is secured the segmental gear Gf. Directly above the gear G is another segmental gear, H, which has a bearing in the locking-arc casting L and alever, I. This lever is supplied with a lever, J, whose fulcrum is at j, and whose upper part is thrust from lever I by spring K, while the lower end is curved and passes through a hole in leverI and enters the holes lin the lockingarc L. By pressing the upper parts of levers J and l together the pin is withdrawn from the hole Z in arc L and the lever I is free to move upon its axis, rotating gears H and Gr andv lifting or lowering the frame ofthe eultivator.

When the cultivator is being drawn to the eld, or in turning at headlands, `the lever I is pushed back, thereby causing the frame and spades to be lifted, so that all shall be clear of the ground but the wheels.v

If the machine is t0 be used as a marker, the lever I is brought to sucha position as to regulate the depth of the furrow; but when used. as a cultivator the lever I is brought forward, which action sinks the spades below the wheels.

. The pole M is held between til) uprights, lo p', projecting upward from the casting I, and is kept down by pin p. To the end of the pole is attached a plate, m. Plate m is hinged to a plate, a, by pin n. Piate n forms a portion of -the lever N, Whose fulcrum is atl O. The end lof lever N plays between aplate, n", and timber C, and is locked in any position by pin n, which passes through holes in plate a and leverA By moving the lever N the direction of the pole M is also changed for the purpose previously given. y

The cultivatoris supplied with a series of spades, S s. The back or rear spades are hinged to castings T, Fig. 3. These castings are composed of a plate, T, having slots t t in it, throughwhich pass set-bolts t t and a projection, T', which supports the spade-standard S by bolt t. he spades next in front of these are hung from the brace-castings V and W, which carry shaft Q. The braceW also supports the locking-arc L. The front spades are hung from castings Uby bolt u, (shown in Fig. 4,) and which are secured upon shaft Q by setscrews q. From one of these castings there is a projection which connects with lever R. By moving this lever the shaft Q slides laterally in its bearings, carrying with-it the spades. All of the spades are braced forward by rods s s.` The casting which supports and guides the pole M is composed of two u rights 9 the base bein somewhat p o 729 7 o of a box sha-pe, provided on the sides with holes p5 p5, through which bolts pass to secure it to the frame-timbers A A. From the bottom there is a projection, p3, to which is bolted a bent piece, p4, upon which rests the doubletree p, and which is held there by a bolt,1o6, which passes through plate p4 and bottom of box. This is shown in Fig. 5.

Having thus described my invention, what IOO I claim as new, and desire to secure by Letters Patent, is-

1. In a cultivato'r, a metallic box-casting, P, secured to the ends of the timbers A A', sub- 5 stantially as shown, and having two uprights, 1J', which are provided with holes and pin lo, between which the pole M rests, and a piece, 1J", between which and the box-casting` P the double-tree is placed and secured by bolt p6,

1o in combination with the pole M and doubletree p, all constructed as shown and described. 2. A box-casting, I?, of the peculiar shape shown and described, havin g two uprights,p, and a projection, p3, cast upon it, in combinai 5 tion with a metallic bar, p4, for the purpose of supporting the cross-tree 19, so that the cultivator is guided by the pole which rests bctween the uprights p, and pulled by the cross- B.
